12 Claims. (o1. 24-2l6) This invention relates to snapv fasteners and particularly, to snap fasteners made from one piece :blanks.

My inventionv contemplates the provision of an inexpensive but efiicient snap fastener comprising a cne'piece socket adapted to be used in connection with comparatively stiff sheet material such as card-board, wood; or the like.

My invention further contemplates the provisionof a simple, inexpensive, one-piece resilient socket adapted tocooperate with a suitable stud and similarly formed of a, flat blank and provided With resilient fingers.

The various objects, of my invention will be clear from the description; which follows and frornithe annexed drawing, in which, i

'Fig. 4 is a plan view ofsa blank from which the studrshown in Figs. 2 and 3maybe made. i Fig. 5. is a. fragmentary plan; view of a modified form of the blank from whichfa slightly modified form, of stud may be made. i

Fig. 6 is a vertical section of the socket shown in Fig. 1. J

Fig. 7 is a bottom planviewof the socket.

Fig. 8- is a plan view of the. blank from which the-socket shown in Figs. 1, 6 and. 7 is made.

In the practical embodiment of my invention which I, have shown by Way of example, and referring to Fig-1, there is shown a one piece socket 10 and a. one piece stud 11 in engagement, The socket and stud are secured, respectively, to sheets of material 12-and 13 which preferably are wood, card-board or other such hard or. stiff material. It will be understood; however, that the socket and stud may; beused in connection with comparatively flexiblematerial such as leather, textiles or the like. Thezstud, 11 is preferably made from a flat blank such as is shown in Fig. 4 and is composed of integral parts suitably shaped to perform their-intended functions. Said parts include the domed-shaped top portion 20, and a; plurality of partly cylindrical side portions 21 depending from the top portion and having edges 22 closely adjacent or in contact with each other.

Extending outwardly from the lower of said side portions is the annular doubled flange portion 23 consisting. of the upper flange 24 and the lower flange 25.. The upper flange as-shown, in

the other alternate radial arms.

Figs. 2 and 4 is provided with a series of projections 26 alternately and cooperating with recesses 27 for the purpose of interlocking said projections and recesses andthereby securing amore rigid structure and preventing lateral distortion of the flange which might occur. under. stress of opera: tion or during the. tumbling operation and at other times. Below the doubled flange .23, thereis atubular portion 28 composedof a series ofcprefa erably abutting cylindrical members, the lower end portions of which are adapted to be bent outwardlyto form the single flange portion 29. To

ternateaprojections 26 are showninterlocked withv the adjacent alternate recesses 27 to providea rigid structure not easily distortediandforming asmooth and uninterrupted continuous: flange.

As shown in Fig. 5, the. same result may; be attained by makinga pair of opposedprojections 26' on each alternate radial arm of the blank; and makinga corresponding pair of recesses 21' on In. Fig. 3, which is a bottom plan view ofthe stud, thesingle flange elements 29 areshown. It will be noted that the elements 29. ofv the blank as shown in Fig. 4 are the only parts of the stud elements which becomeseparatedwhen the stud is secured in place as shown in Fig. 3; that the side portions '28 of the stud; on the contrary, have their edges 30 preferably in contact to form an uninterrupted tube,..as shown in Fig. 1 that the lower parts 25 of the doubled flange 23=likewise have their edges in contact, that the upper parts 24 including the edges of the projections 26 and the recess 27 likewise are in contactto form-an uninterrupted and continuous wall when the blank, as shown in Fig. 4.,is formed into its final shape as shown in Figs. 1 and 2, and also, that the side portions 21 of the upper part of the stud have their edges 22 in contact when the blank 4 is formed into the stud, as shown in Fig." 1; to form a continuous head. The stud l1 accordingly is formed from a onepiece blank as shown in Figs. 4 and 5, and is bent to form integral parts, the edges of which are preferably in contact with each other with the The respective series of Contacting edges 22 and 30 of the stud 11 form slits as distinguished from open spaces which might be called slots. The projections 26 fit into the recess 27 and lend rigidity to the stud 11.

In Figs. 1, 6, 7, and 8 is shown the socket 10 which cooperates with the stud 11 to form my complete snap fastener. Referring to Figs. 1 and 6, the one-piece closed or capped socket 10 is formed from a suitable blank such as the flat blank shown in Fig. 7 in a manner similar to the formation of the stud. The blank is bent to form integral parts including a dome-shaped head 40 to receive and conceal the stud head and having outwardly convex side portions 41.

The side portions 41 have their edges '42 in contact with each other to form slits andto provide a smooth, uninterrupted surface on the resilient socket. Below the side portions 41, there is a comparatively narrow tubular portion consisting of the tubular elements 43, the edges 44 of which are also preferably in contact with each other. To form the securing flange 45, the lower portions of the alternate elements 43 are bent radially outwardly and thereby become spaced from each other.

Integral with the socket are the resilient fingers 46, which are bent within the tubular portion of the socket from the end portions of those elements 43 which are between the elements from which the flange 45 is bent. Said fingers are thereby spacedfroin each other and also arespaced inwardly from the remainders of the tubular elements 43 topermita resilient engagement with the head of the stud 11. The securing'flange 45 and the bulging side portions 41 of'the socket 10 are adapted to receive the sheet 12 between them, the alternate elements 43 being passed through a suitable perforation in the sheet and flanged over on the lower surface of the sheet, thus to secure the socket to the sheet.

It will be noted that the socket 10 is formed from a one piece blank as shown in Fig. 8 which is made with a plurality of radial arms alternating to form the flanges 45v and the resilient The flange extensions are therefore preferably made' longer than the resilient finger extensions. When the socket 10 is formed, the edges of the 'dome'portion as well as the edges of tubular elements preferably contact with each other to form a continuous surface.

.Both the stud 11 and the socket 10 are simple in construction and inexpensive to manufacture.

They form an economical snap fastener well adapted for inexpensive use .as in pencil boxes or cases and the like. They'are rigid and not likely to become distorted and otherwise meet the severe requirements of practicaluse.

While I have shown and described certain specific embodimentsof my invention, it will be understood that I do not intend to limit myself to these embodiments, but that my intention isto claim my invention as broadly as is permitted by the scope of the appended claims and the state of the prior art.-
